The geotagging of (almost) all live shows has been completed, and I have added maps to all the tour pages. For example, see Adore tour#Map. If any coordinates look wrong, you can correct them by editing the page for the corresponding show (or the corresponding venue page, where applicable).
There are also some shows still missing coordinates, if you're interested in helping out. See the list at Category:Live performances with missing coordinates. Most of these I couldn't conclusively figure out what the coordinates are, or they may in fact be intentionally unknown (for instance the shows that took place at private residences).
Cheers and hope you all enjoy this new feature!
